If your neighbour continued to throw rocks on to your roof, what would YOU do? Retaliate?

The thing that no one every discusses is this: What is the root problem between Israel and Palestine. The problems will never cease until we sit down and talk about the actual problem, not the results of the problem. I agree that if someone threw rocks at my house I might be inclined to throw more than rocks back. But why are the rocks being thrown in the first place.
